All women have beta orbiters unless their ugly or fat. And even then.. many still do.
Since pathetic co-dependent betas need female validation like oxygen.. they will chase women post rejection and most women say.. "f*ck it.. why not take advantage? If this loser won't p!ss off... then I'll just exploit his dumb ass."
If you find yourself seriously dating a woman who has guy friends.. just make sure you have plates. Tell her you will lose the plates when she loses the guy friends.
Still.. most women are not worth being "exclusive" with anyway. To be exclusive with most women today is to be a b!tch. Men don't benefit from complete commitment to women in the vast majority of cases.
